The crash happened around 10:30 PM Monday at West County Road and 42nd Street. A Chevy Cavalier was heading west on 42nd when it crashed into the 18-wheeler and ended up under the trailer.
The driver of the Cavalier -- 41 year-old Aimee Ebert -- was taken to the I.C.U. of Medical Center Hospital with a closed head wound and an arm injury.
Troopers tell Big 2 that Ebert ran a red light and may have been drunk at the time of the crash. Troopers say Ebert will get a citation for running the light.
